As usual, starting with the bad news. Caustics are not working in dribble. The tests had irradiance active and that's what I was seeing. Caustics gives an error message.

The export of bumpmaps has been fixed. The code was multiplying amplitude by 10 instead of dividing by 10. Now renders match lightworks for the same amplitude values.

I found the problem with the caustics. Something is wrong with the trueSpace light shaders. I manually replaced them with stock renderman shaders, turned up the intensity and got this:

I was concerned I might have to rewrite a bunch of code. This should be much easier to fix than I thought.

Edit: Nope, I was wrong. The test was using a previously generated caustic file, so I will need to write some code to fix it.
